The six-day floating music festival is delayed after a raid turns up Ecstasy, LSD, mushrooms and marijuana.

Giving a whole new meaning to the term "high seas," the Jam Cruise, a floating six-day music festival that sets sail annually and featured performances by Grateful Dead's Bob Weir, American Idol winner Taylor Hicks, Robert Randolph, Galactic and saxophonist Maceo Parker, was raided by police before it left Florida shores.

A Jan. 4 raid of the 2,550-passenger MSC Poesia turned up small quantities of illegal drugs, including Ecstasy, LSD, mushrooms and marijuana, according to a US Customs and Border Protection spokesperson and the Orlando Sentinel.

Names of those arrested in some 15 seizures have not yet been released, and it's unclear whether any were charged. The Jam Cruise, which featured the return of long dormant jam band God Street Wine, left following the raids and returned on Monday, Jan. 11 without further incident.
